a Bimodal outcome distribution presented to participants in variable outcome and low OD condition, where 80% of outcomes were low in magnitude. b Bimodal outcome distribution presented to participants in the variable outcome and high OD condition, where 80% of outcomes were high in magnitude. c Continuous outcome distribution presented to participants in the low OD condition, where 80% of outcomes were below an outcome value of 50. d Continuous outcome distribution presented to participants in the high OD condition, where 80% of outcomes were above an outcome value of 50
